INTRODUCTIONS

VT Chain  Blocks are a portable lifting device easily operated by hand, which can be attached to a trolley of any type as a traveling chain blocks and one kind of using simply and carrying easily manual hoisting machinery. After absorbing the advanced technology in the world, VT chain blocks are improved on the basis of HSZ series. Except for the traditional characteristics of HSZ series chain hoist, VT series need less hand-pull force, and they are safer, more beautiful and applicable. VT chain blocks adopt high mechanical efficiency and small chain tension and with chains equipped with latches and protection system for safety and security, this series use double pawl, double guide and are also in the framework style. More safety and hand pull lighter.

VT chain blocks are equipped with the most popular block chain--superior grade 80 load chains and forges and heat treated load hooks with batch traceability and stretch indicators, and 360 degree hand rotation with stroke to ratchet indicators. There are also double  pawl brake linings, forged safety latch and sealed roller bearings. With fine and beautiful appearance and reasonable structure, they are environmental-friendly with stable operation and durable in use and service. VT chain blocks are convenient manual lifting machinery, which are suitable for the short distance lifting of small equipment and goods, and the weight is  generally not more than 100 ton. the chain blocks' shell material is highquality alloy steel, strong wear resistance and high safety performance.

VT chain blocks are innovated symmetrical arrayed high speed synchronous gears, and are made of international standard gear steel. Compared with common gears, they are more wearable and steadier, and more laborsaving. The main components are all made of high class alloy steel, with high precision and security. Adopt advanced plastic plating technology inside and outside, it looks like a new one after years of operations. All VT chain blocks have safe and reliable braking functions with gear case and hand wheel cover resistant to external shocks and double enclosure to keep out rain water and dust for a long lifespan.

Load chain in chain block is one of the most critical parts, the abuse that this chain receives can be the difference in a minor accident or a catastrophe, yet it is probably the most overlooked part of a block. Load chain should be inspected daily, weld spatter, a nick, gouge, or stress can greatly reduce the capacity of the load chain. Please inspect your load chain and make sure you always make a safe lift. What’s more, due to the crushing effect grab hooks have upon chain, the design factor of all assemblies must be reduced by 20% for Grab Hook applications. This is a vital type chain block and there are different models such as VC-A, VC, HS-VT, HSZ-VT, HSZ-A622 for this chain block, all means this vital type.

VT chain blocks are widely applied in factories, mines, farms, construction sites, agricultural production, and in wharfs, docks and storages for fixing machines, lifting cargos, loading and unloading goods. They are especially advantageous for lifting work in the open air and places where no power supply is available.

The chain blocks can be attached to a trolley of any type as a traveling chain block. They are also suitable to monorail overhead conveying system, hand travelling crane and jib crane. Our products are widely applied in household, outdoor traveling, aerospace, warehouse, manufacturing industry and construction industry. VT chain block can also be used with all kinds of  manual single-track driving vehicles, which can be used in single rail overhead transportation, manual single-beam bridge crane and cantilever crane.

VT Chain blocks are also called alloyed steel gear VT manual chain  blocks, good price VT type chain blocks with forged hooks, hand tools chain block lifting equipment alloyed steel gear, hand operated hoists, Mechanical hoists and Manual hoists. VT chain block are the hot selling chain block in china market and maybe the most popular manual chain block.

Detailed Description

1. Gear
         Gears are innovated symmetrical arrayed high speed synchronous gears, and  are made of international standard gear steel. Compared with common gears, they are more wearable and steadier, and more laborsaving. Standard international gear steel is two times as wear-resisting degree as the ordinary chain block, rotation is more stable and hand pulling force is lighter. They have high precision toughness gears.

2. Chain
           Adopt high strong chain for strength and practicality including Grade 80  galvanized load chain and hand chain and high precision welding technology, meet ISO3077-1984 international standard. They are fit for gusty overload work conditions; bring your hands a better feeling; multi-angle operation. They change the ordinary chain block only vertical downward  pull and are fit to greater scope. Standard hand chain drop is 2 feet less than lift  (example: 10 foot lift hoist has 8 foot hand chain drop). Standard chain lengths 3mtr & 6mtr with longer drops are available on request.
         Hand Chain: material A3, 30 grades, galvanized (not polished)
         Lifting chain: material 20MN2, G80 grade, black (for bulk order the color is normally black but not galvanized as sample, black is stronger than galvanized, galvanized is just for pretty but loading is somewhat weaker and brittler

3. Hook
         Made of high-class alloy steel, it has high strength and high security by using the new design. and make sure the goods will not be  decoupled. Hooks for Load chain guide mechanism are finely fabricated from wrought iron. Forged swivel hooks with latches reduce twisting of chain and unintentional unhooking of load when chain is slack.

4. Limit switch
           Using limit switch components are in design to protect the chain and ensure the security. Both upper and bottom hooks have limit switch part prevent chain escaping.
5. Components
            The main components are all made of high-class alloy steel, with high precision and security.

           9. there is no relation for 0.5T and 1T, cause hoist body is different (some northern manufacturers use 1T hoist body  instead of 0.5T since they don’t have 0.5T mould)
           there is no relation for 1.5T and 2T, cause hoist body is different
           7.5T and 10T are made up of 1 piece of 5T body, the difference is chain falls and hook
           20T are made up of 2 pieces of 5T body, the difference is chain falls and hook
           [hoist body= chain block body only( bare  block---without load chain and hand chain)]
           5t, 2 chain falls, 1 body
           7.5t, 3 chain falls, 1 body
           10t, 4 chain falls, 1 body
           15t, 6 chain falls, 1 body
           20t, 8 chain falls, 2 bodies
           30t, 12 chain falls, 2 bodies
           50t, 20 chain fall, 2 bodies
